It really helps against insomnia, if you wake some poor android developer halft the world away in the middle of the night to suffer with you - for his implementation of planned obsolence.
E3-1280 v5 goes from 32278.00 Apache requests per second to 25399.47 Requests per second. In other words, a Skylake Xeon performs like an Fx Bulldozer after the patch. And Skylake has the PCID instruction too.
Although to be fair, static-file hosting is about as I/O bound as it gets, and these patches affect file I/O the most.

With server CPUs always being a few generations behind the desktop, this is gonna have massive impact on datacenters.
